Specification of Letters Patent.

Patented June 28, 1910.

Application filed March 24, 1910. Serial No. 551,266.

To all whom it may concern:

Be it known that I, ROBERT MAX MoBIUs, citizen of Canada, residing atSan Diego, in the county of San Diego and State of California, haveinvented certain new and useful Improvements in Sea Power-Generators;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to a sea power generator and has for its objectthe provision of improved means for developing power from the movementof seas, waves and tides, in a constant and regular manner, and toprovide a device of great simplicity of design and durability withsafety in use.

To attain these objects and advantages, the invention consists incertain details of construction and combination of parts, substantiallyas herein illustrated, described and claimed.

Other objects and advantages will become apparent from the detaileddescription which now follows.

In the accompanying drawings illustrating this device, correspondingparts in the several figures are denoted by the same reference numerals.

Figure 1 represents a plan view of a device embodying the principles ofthis in vention. Fig. 2 represents a side elevation. Fig. 3 represents aperspective view.

Referring more particularly to the drawings, numeral 1 designates aplatform mounted upon piling and having bearings 2 mounted thereon andcarrying shafts 3, to which are attached sprocket wheels 4: and smoothpulleys 5. These shafts also carry loose sprocket wheels 6, and 7; thesprocket wheel 6 having ratchet pawls 8 and springs 9 that hold them inengagement with the smooth pulley. Sprocket wheel 7 has ratchet pawls 10and springs 11 that hold them in engagement with the smooth pulley onthe shaft. The ratchet pawls have round ends and are of sufficientlength to bind and grip the smooth pulleys when rotated in the properdirection, and will release themselves when rotated in the oppositedirection, the ratchet pawls being set to grip the pulleys when rotatedin opposite directions, thus imparting motion to the shafts 3, andsprocket wheels 1. For the purpose of securing a more uniform speed ofrevolution, sprocket wheels 4: are made with heavy rims and are adaptedto move chain 12 in a continuous direction with a uniform speed. Chain12 is crossed between the sprocket wheels 4 and drives a ratchet wheel13 upon the power shaft 14:. To secure more uniform motion a heavybalance wheel 15 is mounted on shaft 14:.

To secure power from the waves a frame 16 carrying an adjustable panel17 and mounted in bearings 18 is adapted by means of sprocket chains 19and 20, to drive sprockets 6 and 7 thus connecting the pendulum movementof the panel into mechanical power. Chains 19 and 20, after passingunderneath the platform, are divided into two branches which connectwith the lower corners of frame 16. The panel as shown may beconstructed of wood or be made hollow of sheet metal, and of such weightthat it is submerged to a depth sufficient to give the best results, butadditional means for adjusting the panel are provided in a cable 21which is secured to the center of the panel and passes up through theplatform and over drum 22 which is provided with crank 23 and ratchetpawl 24, thus the panel may be withdrawn from the water entirely or maybe adjusted to receive and transmit the greatest effective powerpossible with this device.

To prevent breakage from a sudden twisting movement of the waves,bearings 18 are made, as illustrated, with a large semicircular top 25,which allows the frame to rise and turn slightly and then resume itsnormal position again.

It is to be understood that the device as herein illustrated anddescribed constitutes a single unit or power generator and the apparatuswill usually be installed with a series of such units, connected to givecontinuous motion to a power shaft and of such size and proportions asmay be deemed advisable. It is also to be understood that the inventionis not limited to the use of sprocket wheels or chains for transmittingpower, but different styles of pulleys and belts or chains may beemployed for this purpose.

While the elements shown and described are well adapted to serve thepurposes for which they are intended, the invention is not limited tothe precise construction and forms as shown, but includes within itspurview such changes in detail as may be employed to embody theprinciples of this invention.

I claim 1. A device of the character described, comprising a platformmounted upon piling, bearings on the platform, a pendulum frame swingingfrom said bearings, a vertically adjustable panel mounted in the frame,means for securing adjustment of the panel comprising a cable, a drumover which the cable passes, a crank for winding the drum and a pawlengaging the shaft of the drum,

frame swinging from said'bearings, chains secured to the top of theframe and passing over ratchet pulleys, to the bottom of the frame, adivision of said chain into two branches which connect with the lowercorners of the frame, and a panel mounted within said frame, incombination with pulleys, chains and a power shaft, substantially asshown.

4. The combination of a platform, bearings upon the platform, pilessupporting the platform, a frame suspended from the bearings, a panelvertically adjustable within the frame, and made of a specific gravitysufficient to submerge the same to the proper depth in the water, chainsattached to the frame and passing over pulleys, pulleys with frictionpawls, shafts driven by the friction pawls, springs holding the pawls inengagement with smooth friction pulleys and means for transmitting thepower from the friction driven shaft to a main power shaft substantiallyas shown.

In testimony whereof, I afliX my signature, in presence of twowitnesses.

ROBERT MAX MOBIUS.
